STONE-QUARRYING MACHINE.

Specification of Letters Patent.

Patented June 12, 1906.

To all whom it may concern:

Be it known that I, EMERSON T. MORRIS, a citizen of the United States,residing at Derwent, in the county of Guernsey and State of Ohio, haveinvented certain new and useful Improvements in Stone-QuarryingMachines, of which the following is a specification.

This invention relates to machines designed for channeling rock, stone,and the like in quarrying, the purpose being to provide a mechanismwhich can be readily set up, taken down, and adjusted to cut blocks orlayers of desired size.

The machine embodies one or more cutters mounted upon a frame so as toreceive a rectilinear reciprocated movement, said frame having impartedthereto a simultaneous vibratory movement at right angles to the lane ofmovement of the cutter to insure the ormation of a channel whereby thelayer or block is completely separated at one side from the mass ofstone.

The invention consists of the novel features, details of construction,and combinations of parts, which hereinafter will be more particularlyset forth, illustrated, and finally claimed.

In the accompanying drawings, forming a part of the specification,Figure 1 is a perspective view 0 a stone-quarr ing machine embodyin theinvention an havin the parts assemb ed for cutting horizonta channels.Fig. 2 is a central longitudinal section of the form of machineillustrated in Fig. 1. Fig. 3 is a transverse section on the line a; :rof Fig. 2 looking in the direction of the arrows. Fig. 4 is a verticalcentral longitudinal section of a stoneuarrying machine embodying theinvention aving the parts arranged for cutting vertical channels. Fig. 5is a transverse section on the line y y of Fig. 4 looking in thedirection of the arrows. Fig. 6 is a detail perspective view of theframework of the form of machine shown in Figs. 4 and 5, supporting thecutting mechanism and the working parts. Fig. 7 is a detail perspectiveview of one of the bits or cutter-points and. the nut cooperatingtherewith. Fig. 8 is a detail view showing the yielding connectionbetween the cutter and the pitman or connection imparting movementthereto. Fig. 9 is a detail perspective View of the connectin meansbetween the movable framework an the fixed structure. Fig. 10 is adetail view of the mechanism for feeding the movable framework andreturning the same to a given position. Fig. 11 is a detail section ofthe cross-head on the line 2 z of Fig. 9.

Corresponding and like parts are referred to in the followin descriptionand indicated in all the views of the drawings by the same referencecharacters.

The fixed framework or structure comprises posts 1, four in number,which are extensible, so as to be rendered stationary when arranged inthe desired position. The posts 1 may consist of ordinary tubing, andeach is provided with a pointed end or section 2-, threaded thereon soas to penetrate the roof or overhead part of a quarry and for theposition of the posts after being positioned. Longitudinal andtransverse rods or bars 3 and 4 connect the posts 1 and form therewith arigid structure. The connecting-rods 3 and 4 are vertically adjustableto admit of moving the cutting mechanism to the required point. Anysuitable means may be employed for firmly connecting the rods to theposts. As shown, a cross-plate 5 is provided at each end of the rods andis centrally depressed, and a companion plate 6, having its middleportion correspondingly depressed, is adapted to be suitably connectedto the plate 5, so as to clamp the post between them.

A movable framework 6" is supported upon the connecting-rods of thestationary frame or rigid structure in such a manner as to have avibratory or reciprocating movement imparted thereto at a right angle tothe plane of movement of the cuttin mechanism, so as to form a channelin the ace or bed of the rock, stone, or like material to be quarried.Arms 7 project from the framework 6 and are loosely mounted uponcorresponding connecting-rods of the stationary framework. A shaft 8mounted in suitable bearings upon a third framework 9, has crankconnection with. one of the connecting rods or bars of the stationaryframe, so as to impart a reciprocati'ng or vibratory motion to theframework 6*. A sleeve 9 is slidably mounted upon the selectedconnecting-rod of the stationary frame, and a pitman 10 connects saidsleeve with the shaft 8 in any manner, so as to impart a reciprocatingmovement to the frame 6 It is to .be understood that the framework 9 isgradually advanced to feed the cutting mechanism as the channel deepens.Hence the necessity for providing a sliding connection between thepitman 10 and the cooperating rod of the stationary frame. A telescopicguide connection is provided between the main or stationary frame andthe movable frame or frames. This connection comprises a rod 11 and atube 12, the latter having a cross head or sleeve 13 at its outer end toreceive the rod 3 of the stationary frame to which said connection isattached. As shown in Fig. 1, a telescopic connection is interposedbetween the frame 6 and the stationary frame and between the frame 9 andsaid stationary frame. The latter connection is slidable upon the rod ofthe main frame, so as not to interfere'with the forward movement of theframe 9 when advancing or feeding the cutting mechanism to its work.This latter connection receives the outer end of the itman 10, facingthe front end of the mac ne, the said pitman and telescopic connectionmoving together as the frame 9 is fed forward to advance the cuttingmechanism.

The frames 6 and 9 may be of any construction best adapted for thespecial work for which the machine is designed. The frame 6 receives avibratory or rectilinear reciprocating movement, whereas the frame 9,being mounted upon the frame 6 and carried thereby, moves in consonancewith said frame and has an independent movement, made necessary to feedthe cutting mechanism as the channel deepens. The framework 9 supportsthe motor 14 and the actuating mec anism for operating the workingparts. The motor 14 may be of any type or structure best adapted for thepurpose. A crankshaft 15, mounted in bearings of the frame 9, derivesmotion from the motor 14 in any manner, and its crank portions areconnected to the cutters 16, so as to impart a reciprocating motionthereto. In the event of the machine being provided with two sets of cutters, so as to form parallel channels at one operation, the connectionsare so arranged as to impart an opposite movement to the cutters, sothat as one advances the other is withdrawn, thereby enabling thecutters to operate in alternation. Each of the cutters 16 is mounted insuitable guides which give rectilinear movement thereto. As shown, eachguide is formed of either a rabbeted strip 52 and a confining-strip 53,attached thereto, or a grooved strip 54. A pitman or connectin -rod 17transmits motion from the crank-shaft 15 to each of the cutters 16 andhas yielding connection with the latter to relieve the operatingmechanism of jar and jolt. This yielding connection is formed by meansof a boxing 18, a block 19, slidable in said boxing, and a spring 20,located at each side of the block. The pitman 17 is connected to theblock 19. Hence power is transmitted from said block through either oneof the springs 20 and boxing 18 to the cutter. This construction enablesthe springs 20 to act as cushions and neutralize all jar incident to theimpact of the cutter with the stone or the like bein cut.

A shaft 21, mounted in suitable bearings upon the frame 9, is adapted tobe driven at a comparatively slow speed for gradually advancing thecutters as the work progresses and is adapted to have a fast speedimparted thereto for quickly returning the cutting mechanism to theinitial or required position after the work has been completed or whenrequired for any purpose. The two speeds may be imparted to the shaft 21in any convenient way. As shown, a shaft 22 has a worm-gear connection23 at one end with the shaft 15 and is provided at its opposite end witha worm-thread 24, in mesh with a wheel 25, fast upon the shaft 21 andprovided with worm-cogs in mesh with the worm-thread 24. For imparting acomparatively fast speed to the shaft 21 a shaft 26 has gear connection27 at one end with the shaft 15 and corresponding gear connection 28 atthe opposite end with the shaft 21. The gear elements 25 and 28 may beeither fast or loose upon the shaft 21, the latter construction beingpreferred and suitable clutches 29 and 30 being provided to throw theminto and out of cooperative engagement with the shaft 21. Anoperating-lever 31 is provided for actuating the clutch 30 to throw thegear-wheel 25 into or out of engagement with the shaft 21. Anoperating-lever 32 is provided for the clutch 29 to admit of throwingthe gearing 28 into or out of action with the shaft 21. One or moreear-wheels 33 are fast upon the shaft .21 and mesh with the teeth of oneor more rack-bars 34, fixed to the framework 6*, whereby when said shaft21 is rotated either forward or backward the framework 9 iscorrespondingly advanced or retracted. When the clutch 30 is inengagement, the shaft 21 is rotated slowly, so as to gradually advancethe framework 9 and the cutting mechanism as the work progresses. Whenthe gearing 28 is clutched to the shaft 21, the latter is rotated at afaster speed, so as to rapidly return the frame 9 to the given orrequired position. It is to be understood that when the clutch 30 is inengagement the clutch 29 is unshipped, and vice versa.

The cutting mechanism comprises a plate or frame 16, provided at one endwith a series of bits or cutting-points 35. The plate or frame 16 isslidably mounted in suitable guides of the framework 6*, as hereinindicated, so as to receive a rectilinear reciprocating movement in aplane at a right angle to the reciprocating or vibratory movement of theframe 6", whereby the bits or cutters 35 form a channel instead of aseries'of openings. Each of the bits or cutters 35 is formed with ashoulder 36, an angular shank 37, and

a reduced threaded end 38 to receive a nut 39, the latter being providedwith radial lugs 40 to receive the taps of a drift or like tool employedfor tightening and loosening the nuts. The plate or frame 16 is providednear its outer end with a series of openings 41, with which otheropenings 42 communicate. The openings 42 are of such conformation as toreceive the angular portions 37 of the bits to prevent possible turningthereof. The openings 41 receive the nuts 39 and the threaded ends 38.The shoulders 36 bear against the front end of the plate or frame 16 andin conjunction with the nuts 39 retain the bits or cutters in place, aswill be readily comprehended.

The machine illustrated in Figs. 1, 2, and 3 is adapted for forminghorizontal channels and for cutting two of such channels at the sametime. The machine shown in Figs. 4, 5, and 6 is adapted for cuttingvertical channels, whereby the layers are cut into blocks. Thearrangement of the parts is substantially the same in both forms, theslight changes being obvious to adapt the operating mechanism to thechanged position of the cutters according as the channels are to be outeither horizontal or vertical. In the machine as adapted for cuttingvertical channels the crank-shaft 15 of the horizontal channelingmachineis dispensed with and is replaced by a shaft 43, which is provided withcrankwheels 44, connected by pitmen 45 with the cutters 16. Shafts 46have a worm-gear connection 47 with the shaft 43, and pitmen or rods 48connect crank-wheels 49 of the shafts 46 with a car 50, mounted to runupon a track of the movable frame 6. Telescoping guides 51 areinterposed between the frame 9 and the car to relieve the pitmen 48 ofundue strain. The shafts 46 are adapt ed to be driven from the motor(not shown) by suitable connections and impart a vertical reciprocatingor vibratory movement to the frame 9, whereby the cutters 16 receive acorresponding movement simultaneous with their longitudinalreciprocating move ment, thereby providing vertical channels instead ofhorizontal. It is contemplated to dispense with one or the other of thecutters, so that when desired a single channel only, either horizontalor vertical, may conform,

thereby adapting the machinefor quarrying rock, stone, or the like inblocks or layers of any desired size.

It is to be understood that motion may be imparted to any one of theconnected shafts for driving the several working parts, the power beingpreferably derived from a motor (not shown) mounted upon the frameworkin substantially the same manner as hereinbefore set forth. For the sakeof illustration a drive-belt 55 transmits motion to the shaft 43. It isto be understood, further, that the working parts may be mounted in anymanner best adapted to meet existing conditions and the special work forwhich the machine is devised.

In the modification shown in Figs. 4, 5, and 6 a framework 56 is mountedupon the longitudinal bars 3 of the fixed framework or structure and isrelatively stationary and embodies longitudinal sills 57, upon which thecar 50 is adapted to travel. The movable framework 6*" is mounted uponthe frame work 56, so as to receive a vertical reciprocating movementonly, and the rack-bars 34 are firmly attached thereto and mesh with thegear-wheels 33 to effect forward movement of the car 50 and the frame 9in the operation of the machine. The cutters 16 are directed in theirreciprocating movements by guides applied to and forming a part of theframework 9. The framework 9 supports the driving mechanism andreciprocates vertically with the framework 6" and is in turn advancedwith the car 50 to feed the cutting mechanism to the work.
